 February Number of the Geological Magazine : as they refer to that 

 portion of the district, in which, he says, Professor Sedgwick 

 "appears to have lost sight of" the formation. 



In the quarry at South Stainley, to which reference is made, and 

 of which the following is a section, the upper beds consist of flaggy 

 Grits, separated from the more compact Grits below by a bed of Eed 

 Sandy Clay, about a foot in thickness. The dip is to the N.W. at 

 an angle varying from 3° to 6°.

About a mile and a quarter due west is a quarry, now disused, in 

 which the beds as they lie, with an inclination 30° S., are broken 

 and split at their edges, and covered with a gTavel of disiategrated 

 Sandstone.

Half a mile to the S.W. of this quarry is another at Kettlespring, 

 of which the upper beds consist of flaggy Grits, to the thickness of 

 about 5 feet, lying upon the Eed Grit, the beds of which become 

 gradually harder as they descend. In this quarry, and in the one at 

 South Stainley, and also on the rock to the north of Fountain's 

 Abbey, the face of the rock is occasionally covered with Calcareous 

 Spar, indicating the former presence of overlying Manganesian 

 Limestone. A little above the village of Shaw Mills, in the same 

 valley, is another quarry, in which the strata dip to the S.W. at an 

 angle of 45°. There the Grit contains small pieces of Coal, evi-
